This an awesome cookie recipe...I made some changes...I added 1/4 cup flour...I replaced some on the vanilla with 1/4 teaspoon almond extract..baked for ten minutes @ 380 degrees..the most important part of this recipe is do not over mix the dough..I added the flour mixture gradually and mixed with a fork...I refrigerated the dough for about a hour...I have been looking for the ultimate cookie recipe for the holidays this one is on my list
